Prestige APS775 - Shock sensor during RS

Hey everyone, I've had an APS775 for about two years, and I was wanting to know if there was a way to shunt the shock sensor while under remote start command? It always bugged me that if I accidentally left my radio on, or if my a/c was on it would trip the alarm. I'm pretty sure this model is supposed to automatically do it, but it ain't... If any assistance can be provided, I would be much abliged... -Sean

Yeah, the Audiovox manual says that it ignores the shock sensor during remote start. In reality, it just ignores the sensor for about the first five seconds---since the engine shakes the most while cranking----then it resumes monitoring the sensor again. Also, I have only seen a handful of cars that require the remote starter to also power up the radio circuitry. Unless I have to, I never power the radio on my installs. But anyway, to answer your question. There are two solutions. I think #2 is slicker, but it's your choice. 1. Use the Audiovox's light blue "ignition 3" output to trigger a relay. Use the relay to interrupt either the black or the red wire at the shock sensor. (The ignition 3 output provides a ground the whole time the remote starter is on.) 2. The black wire at the shock sensor is for ground. Cut the black wire a couple inches from the brain. Strip the end of the black wire that's coming from the shock sensor, and connect it to one of the car's ignition wires. Or tap it onto the Audiovox's large blue ignition wire, whichever is easier. When the ignition is on, the shock sensor will have no ground, and therefore it won't operate. But when the ignition is off, it will rest at ground---not a true, perfect ground---but plenty good enough for the shock sensor to work.
